Caution in handling of media
2016-04-08 17:48:26

When using a digital flatbed UV printer, there is not doubt that you should use a medium. The passage is to tell you some tips about this. When you handle the UV printer media,you should pay attention to followings

1.Extension and shrinkage of the media

Do not use the media in the sheet form shortly after the package was opened. The media could extend or shrink depending on the temperature and humidity inside the room. For more than 30 minutes after opening of the package, the media has to be exposed to the ambient air of the location it is to be used.

2.Warping of the media

As for the media of the sheet form, use the flat one, or the one warping downward (the one with floating central part when placed the printing surface facing upward.) The media warping upward could not be absorbed in some cases onto the table. Store the media liable to be warped on the slightly smaller platform or palette so that it may warp downward. Be careful not to warp the media out of the absorption area.

3.Absorption of the UV printing media

To maintain the absorption effect, cover the suction holes not covered by the media with other media which is thinner than the media.

4.Other precautions

a)Do not place any article on the surface of the coated paper. Some coated paper could change its color.

b)Curled media that cannot be absorbed or the media that has a dislocation when the Y-bar is moved may not be used. Before using, fix the media with adhesive tape, etc.

c) Do not use the media that will generate warping or deformation even if the logical seek is set“OFF”.

d) As the bed surface is constructed of multiple boards, their joint lines could be reflected on the printed images depending on the thickness and elasticity of the UV printing media. Similarly, the suction holes could affect the printed images. Perform the printing after confirming that there is no problem by making the test printing in advance.
